Fan clutch W124 1988
 

I would like to thanks the member (whom I forgot the name) who gave, to my point of view the solution for adjusting the temperature of engagement of the fan clutch, ie to reduce the lenght of the pin by a few 1/10 of millimiters). I did it on my car, 260E, 1988, together with a straitning of the temperature spring plate and the result is absolutely perfect. In traffic jams the temperature does not go beyond 100° and stay around 82 degrees on the ride.

This forum is absolutely great

regards

Shortening the pin seems like a good idea; however, I wouldn't have chosen to bend the spring plate. By doing so, you may have weakened it and if so, it won't necessarily consistantly pop back and forth at the same temperature. Just keep an eye your temp gauge.

Indeed there are two solutions,

Shortening the pin is a no return solution,

I found more difficult to achieve the right setting with the binding of the plate because by design it has certainly been made flat.

I have driven 2000 km and every thing is fine.

Hi to all,

I have driven now 10 000km with this and it is perfectly working

With your current location, the 103 motor in that climate should not be reaching 100C...

I would look into figuring out what is wrong with the cooling system.

First check the level is correct, second check for pressure in the system and at the cap. If both check out properly, your water pump may be on its way out and the lack of pressure is the cause of running hot. Just watch out because the weep hole could suddenly start gushing.

I think it was just a fan clutch at the limit of specifications, because the shop who sold the fan had replaced it once for the same high functionning temperature.
Now that I did this adaptation (shortning the pin), it is perfectly working even in hot European temperatures (38 degrees).
